You have an Exchange Server 2010 organization.
You need to determine why a remote SMTP server rejects email sent from your organization.
What should you do?
A.
Review the application event logs.
B.
Review the message tracking logs.
C.
Set the Protocol logging level to Verbose on the Receive connectors and then review the protocol log files.
D.
Set the Protocol logging level to Verbose on the Send connectors and then review the protocol log files.
Explanation:
Protocol logging records the SMTP conversations that occur between email servers as part of message delivery. These SMTP conversations occur on Send connectors and Receive connectors configured on servers running Microsoft Exchange Server 2010 that have the Hub Transport server role or the Edge Transport server role installed. You can use protocol logging to diagnose mail flow problems.Reference:
